What is this release trying to address?
CLAMP .....
Use Cases
The existing use cases are still going to be supported and additional use cases will be supported for the CasablancaRelease (as defined by the Control loop sub committee)
Minimum Viable Product
The minimum viable product that we aim to reach within R3 is to have the CLAMP application Beijing(R2) features at least running in the new UI separation model.
Functionalities
List the functionalities that this release is committing to deliver by providing a link to JIRA Epics and Stories. In the JIRA Priority field, specify the priority (either High, Medium, Low). The priority will be used in case de-scoping is required. Don't assign High priority to all functionalities.

Stories
want to consolidate Beijing achievement by
- achieve the Casablanca S3P requirement for Casablanca in the limits the available resources permit.
- making the support of new micro-service generic(no code development needed to support new mS)
- using service template as Tosca as artifact received from DCAE-D to describe the Control Loop flow
CLAMP will also support the auto scale out of VF-module use case.
Use Cases
The existing use cases are still going to be supported and additional use cases will be supported for the Casablanca Release (as defined by the Control loop sub committee: auto-scale out use case)
Minimum Viable Product
The minimum viable product that we aim to reach within R3 is to have the CLAMP application Beijing(R2) features at least running with the new service template as artifact exchanged between CLAMP and DCAE-D.

Longer term Roadmap
Indicate at a high level the longer term roadmap. This is to put things into the big perspective.
The long term goal is to reach a common platform for managing control loops within ONAP :
CLAMP is a platform for designing and managing control loops. It is used to design a closed loop, configure it with specific parameters for a particular network service, then deploying and undeploying it. Once deployed, the user can also update the loop with new parameters during runtime, CLAMP is a platform for designing and managing control loops. It is used to design a closed loop, configure it with specific parameters for a particular network service, then deploying and undeploying it. Once deployed, the user can also update the loop with new parameters during runtime, as well as suspending and restarting it.
...
Another Key long term goal is to provide a better user experience by separating clearly the UI in 2 entities : one for the design time and one for the runtimehaving more flexibility to add mico-service without code development.
A Dashboard is also going to be has been introduced to allow the user to get a quick overview of the status of running control loops.
...
The other ONAP projects CLAMP depends on are:
- SDC/DCAE-D : Rest based interface exposed by the SDC, Distribution of service to DCAE + SDC UX UI SDKDistribution of Templates to CLAMP via SDC distribution client jar
- DCAE: Rest based interface exposed by DCAE, Common Controller Framework, DCAE microservices onboarded (TCA, Stringmatch, Holmes (optional))
- Policy: Rest based interface (the Policy team provide a "jar" to handle the communication), both XACML and Drools PDP, APIs to App-C/VF-C/SDN-C
- DMaaP: Message bus within DCAE and cross-ONAP
- VNF use cases : defines what type(s) of control loop(s) can be implemented and configured by CLAMP
...
•CLAMP is separated in 2 areas, which are currently (in seed code) both supported by a single application:
- Design Time(Cockpit/UI to define to Configure the templates)
- the Templates are pushed to (service template) are defined in DCAE-D and distributed to CLAMP by SDC. The template templates format is TOSCA blueprint, those blueprints will be pushed/provisioned. Aside of the service template the corresponding blueprint is also generated by DCAE-D and pushed, by SDC, to DCAE orchestration engine.
- policies (configuration and operational policies) are pushed/provisioned towards the Policy Component of ONAP. (those policies will be triggered by DCAE during Closed Loop operations).
- The DCAE team needs to provide models to Policy team in order for the Configuration policy to be built.
- Run time(DCAE-Policy, grabbing events and triggering policies based actions)
- In the first release of CLAMP, the triggering to deploy(and then effectively start the closed loop) a blueprint will be manual (via CLAMP cockpit) an automatic deployment based on an event will come in future release.
- The CLAMP cockpit will support the following action at runtime:
- start (start the provisioned Closed Loop on DCAE)
- stop (stop a provisioned Closed loop on DCAE)
